What is tinnitus?
In addition to ringing in the ears, other symptoms associated with tinnitus may include:
- Stress due to fear of tinnitus
- Ear pain
- Difficulty sleeping
- Difficulty concentrating
- Decreased hearing
Persistent unexplained tinnitus is evaluated with a hearing test (audiogram). Measures can be taken to lessen the intensity of tinnitus.
What causes tinnitus?
Tinnitus is a symptom, not a disease, and it has a variety of causes that may arise anywhere in the hearing mechanism. It begins in the ear with the tympanic membrane and the cochlea, where the sound is transmitted and transformed into electrical energy for the brain to perceive.
- Blood flow and/or tumors: Throbbing Tinnitus (pulsatile) may be due to blood flow through arteries and veins adjacent to the ear, as well as vascular tumors, meaning that they have increased blood flow within them.
- Muscle spasms: Tinnitus that is described as clicking may be due to abnormalities that cause the muscle in the roof of the mouth (palate) to go into spasm. This causes the Eustachian tube, which helps equalize pressure in the ears, to repeatedly open and close. Multiple sclerosis and other neurologic diseases that are associated with muscle spasms may also be a cause of tinnitus, as they may lead to spasms of certain muscles in the middle ear that can cause repetitive clicking.
- Temporomandibular joint (TMJ) abnormalities may cause a repeated clicking sound in the ear.
- Damage to the vestibulocochlear nerve: Damage to the vestibulocochlear nerve responsible for transmitting sound from the ear to the brain may cause tinnitus. Causes may include drug toxicity or a tumor (for example, acoustic neuroma).
- Meniere's disease, which is associated with hearing loss and vertigo also may cause tinnitus.
- Aging: As people age, their hearing may decrease and there can be associated tinnitus.
- Otosclerosis: Otosclerosis, which is caused by abnormal bone growth in the middle ear, can sometimes cause tinnitus.
- Trauma may also be a cause of tinnitus and hearing loss. This includes barotrauma, whereby air pressure changes can damage ear function. Examples of barotrauma include pressure changes from scuba diving or changes in air pressure when flying.
What are the symptoms of tinnitus?
Tinnitus may present as the following symptoms:
- The sound of tinnitus may be constant or it may come and go intermittently.
- It may be throbbing.
- It may occur in one ear or both ears.
- Most often, the sound is a high-pitched continuous tone, but it may also be described by the patient as a click, buzz, or hum.
Tinnitus is often associated with hearing loss and the patient may complain of decreased hearing, even if the tinnitus is absent.
What kind of doctors diagnose and treat tinnitus?
Often tinnitus can be evaluated by a primary care doctor or internist, but if consultation is needed, an otolaryngologist (ear, nose, and throat doctor) is the specialist who evaluates and cares for people with tinnitus.
Audiologists are trained to perform hearing tests and assessments.
How is tinnitus diagnosed?
The patient's history and description of symptoms are the keys to determining what might be causing tinnitus.
The healthcare professional may ask questions regarding the quality of the abnormal sound, and whether it is constantly present or whether it comes and goes. Other questions may include the following:
- Does it involve one or both ears?
- Does the sound pulsate, or does it sound like a rush or flow?
- Does it click?
- Has there been recurrent exposure to loud noises or sounds at work, at home, or at play?
- Is there associated decreased hearing or hearing loss?
- Does the person feel a sensation of spinning (vertigo)?
Diagnosis of tinnitus may include the following:
- Medications: Be prepared to provide the healthcare professional with a list of medications including over-the-counter (OTC) and supplements to review since tinnitus may be a side effect of certain medications.
- Physical exam: Physical examination will focus on the head and neck, and especially the ears, including the auditory canals and tympanic membranes. Since the sense of hearing is conducted through one of the cranial nerves (the short nerves that lead directly from the brain to the face, head, and neck), a careful neurologic exam also may be performed. Weakness or numbness in the face, mouth, and neck may be associated with a tumor or other structural abnormality pressing on a nerve. The healthcare professional may listen to the flow in the carotid arteries in the neck for an abnormal sound (bruit) since carotid artery stenosis (narrowing of the artery) can transmit a sound to the ear that may cause tinnitus.
- Hearing test: An audiogram or hearing test may be performed to look for associated hearing loss in one or both ears.
- Imaging: Depending upon the suspected underlying cause of tinnitus, radiology tests may be performed to image the head and neck, including the structures of the ear. These imaging tests may include CT scans, MRIs, and ultrasounds.
- Referral to a specialist: Consultation with the appropriate specialist may be needed, both for diagnosis and treatment.
What are the treatments for tinnitus?
Tinnitus is a common complaint, with up to 15% of Americans experiencing it. It is the most common symptom reported by military service members returning from combat.
- Tinnitus may last for weeks or months and then resolve spontaneously. For some people, tinnitus may last for years.
- The tinnitus may be significant enough to interfere with an individual's activities of daily living. For this reason, treatment must also be directed at decreasing the effects of tinnitus on a person's daily life, such as depression, insomnia, etc.
- For those people whose tinnitus is caused by an adverse or toxic reaction to a medication, stopping the drug may allow the hearing mechanism to recover; however, talk with your doctor before stopping any medication. Sometimes the adverse effects of medications on hearing may be permanent.
- Electrical stimulation and repetitive transcranial magnetic stimulation are some of the other treatment considerations available for certain individuals with tinnitus.
What medications treat tinnitus?
Medications used to treat tinnitus may include the following:
- Benzodiazepine medications, including alprazolam (Xanax), may help suppress nerve function and decrease tinnitus symptoms.
- Corticosteroid injections into the middle ear may decrease inflammation in certain cases of tinnitus.
- Antidepressant medications may decrease the intensity of tinnitus or resolve the noise altogether. Moreover, antidepressants may also help with the depression that is sometimes associated with the presence of persistent and chronic tinnitus.
- Prostaglandin analogs, such as misoprostol (Cytotec), may be of some help in some people with tinnitus.

What is retraining therapy and relief therapy?
There are some behavioral and cognitive therapies that have been successful in treating tinnitus. Seeking out a multidisciplinary program at a medical center that specializes in tinnitus may improve treatment success.
Tinnitus retraining therapy is a form of treatment that tries to retrain the nerve pathways associated with hearing that may allow the brain to get used to abnormal sounds. Habituation allows the brain to ignore the tinnitus noise signal, and it allows the person to become unaware that it is present unless they specifically concentrate on the noise. This treatment involves counseling and wearing a sound generator. Audiologists and otolaryngologists often work together in offering this treatment.
In addition to tinnitus retraining therapy, other treatments exist that attempt to relieve tinnitus such as relief therapy, and each affected individual may benefit differently depending upon the cause of the tinnitus and their response to treatment.
Some other treatment options include the following:
- Stress reduction
- Depression counseling
- Electrical stimulation for patients with hearing loss
Does acupuncture treat tinnitus symptoms?
While scientific research has not shown the benefit of acupuncture in the treatment of tinnitus, there may be a significant positive placebo effect.
Can tinnitus be prevented?
Repeated loud noise exposure can be a cause of tinnitus as well as hearing loss. Loud music may cause short-term symptoms, but repeated occupational exposure (for example, musicians, factory, and construction workers) requires less intense sound levels to cause potential hearing damage leading to tinnitus. Minimizing sound exposure, therefore, decreases the risk of developing tinnitus. Sound protection equipment, like acoustic ear-muffs, may be appropriate at work and home when exposed to loud noises.
A variety of medications may be ototoxic (damage the ear) and cause tinnitus. If tinnitus develops while you are taking medication, stop the medication and discuss other options with your healthcare professional.
What is being done in research on tinnitus treatments?
Tinnitus remains a symptom that affects the lives of millions of people. Research is directed not only at its treatment but also at understanding why it occurs. Research doctors at the University at Buffalo, The State University of New York, Dalhousie University (Canada), and Southeast China University have published research using electrophysiology and functional MRI to better understand what parts of the brain are involved in hearing and the production of tinnitus. Their research has found that much larger areas of the brain are involved with the process of hearing than previously believed, which may help direct future diagnostic and therapeutic options.

CT Scan (Computerized Tomography)A CT scan is an X-ray procedure that combines many X-ray images with the aid of a computer to generate cross-sectional and three-dimensional images of internal organs and structures of the body. A CT scan is a low-risk procedure. Contrast material may be injected into a vein or the spinal fluid to enhance the scan.
Illustrations of the EarThere are three sections of the ear, according to the anatomy textbooks. They are the outer ear, the middle ear, and the inner ear. See a picture of Ear Anatomy and learn more about the health topic.
Earwax RemovalEarwax (ear wax) is a natural substance secreted by special glands in the skin on the outer part of the ear canal. It repels water, and traps dust and sand particles. Usually a small amount of wax accumulates, dries up, and then falls out of the ear canal carrying with it unwanted particles. Under ideal circumstances, you should never have to clean your ear canals. The absence of ear wax may result in dry, itchy ears, and even infection. Ear wax may accumulate in the ear for a variety of reasons including; narrowing of the ear canal, production of less ear wax due to aging, or an overproduction of ear wax in response to trauma or blockage within the ear canal.
Eustachian Tube DysfunctionThe Eustachian tube is a membrane-lined tube that connects the middle ear space to the back of the nose. Symptoms of Eustachian tube dysfunction or blockage include popping and/or clicking in the ear, and ear fullness and/or pain. Causes of Eustachian tube dysfunction or blockage include allergies, sinus infections, ear infections, and the common cold. Treatment includes home remedies to relieve pain and several maneuvers (swallowing, chewing gum, yawning, etc.), which can be done to improve Eustachian tube function. In severe cases, surgery may be necessary.
How Can I Unclog My Ears at Home?Clogged or stuffy ears may cause considerable discomfort that includes ear fullness, dizziness, muffled hearing, ringing in the ears and ear pain. Home remedies to unclog your ears include chewing, ear irrigation, performing the Valsalva maneuver, applying warm compresses, using OTC nasal decongestants or or putting oil drops or hydrogen peroxide into the affected ear.
Inner Ear Infection (Labyrinthitis)Labyrinthitis occurs when there is inflammation of the part of the ear responsible for balance and hearing), usually due to viral infections of the inner ear. Learn about causes, symptoms, and treatment.
MRI (Magnetic Resonance Imaging Scan)MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.
A perforated (ruptured, punctured) eardrum (tympanic membrane) is a hole or tear in the eardrum. The eardrum separates the ear canal and middle ear. Most ruptured eardrums do not cause pain, however, the condition can be uncomfortable. Bacteria, viral, and fungal infections are the most common causes a ruptured eardrum. Earwax removal attempts, changes in air pressure, and trauma are other causes of a ruptured eardrum.
If you have a ruptured eardrum you may have symptoms like:
- Ear pain
- Partial or full hearing loss
- A mucousy or pus-like blood-tinged discharge from you ear
- Bleeding from the ear
- Ringing in the ear
- Middle ear infection
Most people do not need medical treatment for a ruptured eardrum, however, some may need surgery depending upon the cause and size of the hole in the eardrum.

What Can Trigger Vertigo?Vertigo is the sensation of spinning or rocking, even when someone is at rest. Vertigo may be caused by a problem in the brain or spinal cord or a problem within in the inner ear. Head injuries, certain medications, and female gender are associated with a higher risk of vertigo. Medical history, a physical exam, and sometimes an MRI or CT scan are required to diagnose vertigo. The treatment of vertigo may include medication, special exercises to reposition loose crystals in the inner ear, or exercises designed to help the patient re-establish a sense of equilibrium. Controlling risk factors for stroke (blood pressure, weight, cholesterol, and blood glucose) may decrease the risk of developing vertigo.
